tion, .in the manner Ishown lin' Fig. v2, so that the teeth onone plate may Iswingwithin the spaces 'between the teeth onthe other plate as the shovel plates are actuated Tto 'effect their 'shoveling function.

The means for driving the shovel mechanism, :shown lin-Figs. 7 and `9, comprises a vertically Idisposed tubular shaft 82 journaled at its lower 'within the hub fof 'the bevel gear M, in coaxial relation with the latter, vand at its upper vend within the hub of a chain sprocket 83. The shaft 82 isconnectble to the bevel gear 44 -by `a sliding vJaw clutch '84 splined to the shaff-t 8'2 and Ahaving clutch teeth engageable with clutch teeth on the bevel gear hub.Y The 'chain sprocket `83 has a hub journaled vat 85 within the machine frame, and a collar '85 secured tothe chain sprocket hub maintains the sprocket in position within its bearing. Surrounding the shaft B2 and interposed between the jaw clutch 84 and 'the collar B6 is a coil spring 81 which constantly` urges the jaw clutch toward its lcwermost clutched position. The jaw clutch is releasable against the tension of the coiled spring by means of a vertical operating rod 88 guided for axial sliding movement within the machine fram'euand vhaving its threaded upper end 89 engaging-a nut Si). nut rotatably engages a bracket 8| secured to the machine frame, and has a conveniently located operating handle 92. When the nutis rotated the operating rod may be 'moved Yvertically up'- wardly to effect clutch release, thereby to disconnect the chain sprocket 83 from driven, relation with the bevel gear 44. As'illustrated, the chain sprocket 83 is connected by an endless drive .chain 93 extending through the upper portion of the machine frar'ne, to a chain sprocket 94, herein formed integral with the upper crankdisc 68. As shown in Fig. f7, the crank discs are keyed to a vertical shaft 95 suitably journaled within the machine frame, so that the upper crank disc may effect drive, through the shaft 95,. of the lover crank disc |59. It will thus be seeny th`atwhen the jaw clutch 84 is connected thejsliovel mechanism may be driven vby the motor Stl'ircug'h the spur'g'earing I2, I3, shaft I4', double gearing' 43V, M, clutch 84, shaft 82, chain sprocket 83, drive chain 93, chain sprocket 91 'arid the crank discs sa, es, and arms sa and 64.

As is usual in coal mining" machines of the longwall type, the cutter M may be abOut its pVOf from' al DSJ. iitedlhgvlhgth- Wise-Y of the machine frame, to right-angle 7positions at either side of the machine'frame; andthe cutter bar has a conventional hanger" framegfindica-ted in dotted linesy at 95l inf Fig. 7, which en'-v gages the projecting portion 4010i the machine' frame; and carried' by the hanger frame' is al locking devicel 91, such as' a friction clamp; for locking the cutter bar in' any of its adjustedA posi-v tions.k Mounted on thetop of the mach-ine frame along one side of the latter is a guide bar r|01) having a vertical flange |=0| engag'ealoley withtther coal face for guiding the machine during movement ofthe latter along the coal face during'the cutting and loading operations. Thisv guide bar hasinwardly bent ends |'02-tofacilitate movement thereof along' the coal face,r and the' horizontal` overlying portion |03'ofl the guide bar 'is' providedwith transverse slots1|04 through'fwhich' F tightening` screws |05l threaded within the tcp` ofathefmachine frame; pass: These slc-t'spermit lateral,` adjustment of the' guide bar? with respect to the'machinerframe into engagement with'the" coal.' face, and'A the screws lllgvwhen tig'hten'e'c'l;

The-

f 56 and 51 respectively, are verticald'elec'zto'r-` plates- 'lines' in Fig. 1. yThe active deiiector plate |08v at the side of the machine@ remote from'thecoal face may be swung outwardly" into the positionshown in' Fig." 1, andheld in suchposition by meansof` a brace rod l'pivota'lly connected at |101 vto the adjacent side ofthe machiner frame. This brace rod has sliding'telesc'opic engagement 'pwitha tubular member' I ll'pivotally connected at ||2 to the deflector plate. As the deflector plate |08 is swung laterally into its different adjusted positions with'respect to theside of the machine frame; the Vrod |09-tele'scopesv with re'- w spect to the member I I I, and when the parts are properly-adjusted ascrew II3'may betighten'd' to hold the parts in adjusted position.'4 The fdeecto'r plate |01has 'a similar brace rod arrangement.

As the machine moves along the" co'al faceto effect its cutting and loading-operation, thesliovel mechanism gathers v'the looseco'al previously shot' down on the mine-floor adjacent the coal face and moves the loose coal 'laterally away from' the coal `face out of the pathof movement of the machine,zand'the defiector plate lfdee'cts the coal, as itis dischargedV from kthe shovel mecha# nism; in a lateral direction'away from'thema-` chine.'V Inithisinstancepthe vdeiiected coal is re` ceived by aconventional Yface conveyor I l|4"'laid onthe mlne'yoor between'the machine-andthe" roof Aprops at-the side' of the machine remote from the/coal` faceyand thisxconveyo'r may move lthe loose coal away from the 'machine'to-.a suitable .frame is providedwith threaded apertures-tore;

It will further lbe noted that portions of theV operating mecha nism are illustrated in a somewhat simplified iorm,and that changes in proportions to handlev heavy loads may be made without departing from the present invention. l

. Thelrnode of operation-olfv improvedY cutting v andina-ding machine will be clearly apparent When ,the 'mining machine is being moved about the mine under the propulsion of the track-laying treads, the

shovel mechanism is; preferably -in its centrally locatedvposition Yand `the cutter bargis disposed" lengthwise of the machine, as indicatedfin' dotted lines in Fig; 1. As the machine is propelled about the mine byttheA tractor-tread mechanism ,it may beV steered by varying the relative, speeds of the planetary `gearings 24', 25 26 under the control of the brake shoes 28, itfbeing possible by speeding upthe driveof one tractor treada'nd, slow- Vingdown the drive for -the otherto eiect turn ing movements offthe machinefin a well known manner.
